We now know that Russian operatives exploited Facebook and other social media to sow division and undermine the election of 2016, and special counsel Robert Mueller recently indicted Russian nationals and Russian entities for this activity. During that period, however, Facebook executives kept their heads down, and the C.E.O., Mark Zuckerberg, denied and underplayed the extent of the damage. Now Zuckerberg is in a process of soul-searching, attempting to right Facebook’s missteps—even if it means less traffic to the site. Nicholas Thompson, the editor in chief of Wired (formerly the editor of NewYorker.com), interviewed fifty-one current and former employees of Facebook for a Wired cover story, co-written with Fred Vogelstein, called “Inside the Two Years that Shook Facebook—and the World.” He tells David Remnick that the effort is not just lip service: for a business like Facebook, reputation really is everything.
